| 2.1 Open a seismic-data file with field geometry encoded [e.g., *(SR).dat]. |
| 2.2 Click "Run AUTO" button. |
| 2.3 Final 2D S-velocity (Vs) cross section is displayed at the end of the process. |
| 3. AUTO on Dispersion Image Chart |

| 3.1 Open a dispersion-image file [*(OT).dat] to get dispersion curve(s) (*.DC) |
| 3.2 Click "AUTO" button. |
| 3.3 A dispersion curve is automatically extracted. Click "Save" button to save the curve. |
| 3.4 The extracted curve can be edited, if necessary, using the mouse before it is saved. |
